Combine any like terms in the expression. If there are no like terms, rewrite the expression. \( 36 a^{3} b^{3}+25 a^{3} b^{3}+23 a^{3} b^{3}-27 a^{3} b^{3} \) Submit

We start with the expression: \[ 36 a^{3} b^{3}+25 a^{3} b^{3}+23 a^{3} b^{3}-27 a^{3} b^{3} \] Since all terms contain the factor \(a^{3} b^{3}\), we can factor it out: \[ a^{3} b^{3} \left(36+25+23-27\right) \] Now, combine the coefficients inside the parentheses: \[ 36+25=61 \] \[ 61+23=84 \] \[ 84-27=57 \] Thus, the expression simplifies to: \[ 57 a^{3} b^{3} \]
